■ Precaution on Use
1. Adjust the track often enough to keep a
proper tension.
Insufficient tension slips off the rubber track
shoe and wears out the sprocket and iron
core extremely.
Excessive tension increases travel
resistance, which prevents proper travel
force and speed. It also causes damages
and extreme wear at undercarriage as well
as overextension of the rubber track shoe.
2. To prevent damages of the rubber track
shoe, avoid the following in travel as much
as possible.
Pointed rocks or quarry
Craggy place such as riverbed or path
through woods
Steel rods or scraps
Steel board or cornered objects of
concrete
Heat source such as acre
Travel in contact with concrete path or wall
3. Immediately wipe off spilt fuel, hydraulic oil,
or grease on the rubber track shoe with a
cloth.
4. Avoid sudden spot turns or pivot turns.
Make slow turns several times at a low
speed.
5. Do not use for long (3 months or more).
Store it to avoid direct sunlight or rain.
6. Use the rubber track shoe at a temperature
between -25°C and +55°C (-13°F and
131°F) because of a rubber’s characteristic.
